In the following we assume that the latest version is 1.0.14. Please change this in accordance with the one you downloaded from the Alsa project site. • • • • Setup installation directories sudo mkdir -p /usr/src/alsa cd /usr/src/alsa sudo cp ~/downloads/alsa*. Sudo tar xjf alsa-driver*.bz2 sudo tar xjf alsa-lib*.tar.bz2 sudo tar xjf alsa-utils*.tar.bz2 • Compile and install alsa-driver cd alsa-driver* sudo./configure --with-cards=hda-intel --with-kernel=/usr/src/linux-headers-$(uname -r) sudo make sudo make install -- The configure step fails in Ubuntu 8.10 with the kernel 2.6.27-7. The configure script is unable to find the autoconf.h file and complains that it wants the full kernel sources.
